%X By the methods of remote sensing(RS) and geographic information system(GIS),and based on the estimations of degradation degree,risk degree and easy-restoration degree of degraded grasslands,an ecological management index(EMI) model of grassland was established to approach the practical ways of optimizing management of degraded grassland.A case study in the Xilin River Basin of Inner Mongolia showed that this model could quantitatively analyze the degradation degree,risk degree and easy-restoration degree of the grasslands under different optimizing management levels,which was of significance for applying rational measures with pertinence,and beneficial to the optimal allocation of resources during the management of degraded grassland.The EMI model could integrate most concerned information,which made it applicable widely.
